The place was pretty much perfect. The internet was blazing fast, the location was perfect (few minutes to the BTS, 24 hour convenience stores and food nearby). The place itself is what you'd expect (safe, ac, washer/dryer unit, etc.), and that alone would warrant a 5 star review.
The unexpected and best part of the unit though was the hosts. They accommodated my incredibly late arrival, had snacks/fruit there on my arrival in the unit, and the best part was the hosts responsiveness. I'm not sure when she sleeps but I messaged a couple times with questions unrelated to the condo and I got replies within a minute even late at night. With the hosts availability and bending over backwards to help, the condo essentially comes with a 24 hour private concierge.
On my next stop I'll definitely be staying at one of their places. I've had paid assistants that were less helpful and responsive. I'd give 6 stars if I could.
